Hi Dr Santhosh
Thank you for your question to HCM.
Muscle spasm is possibly a result of your weight lifting activity. From your description you back pain
seems very likely from muscle strain
. MRI is sensitive to detect pathological lesions in the spine causing back pain. Disc bulges with nerve
compression commonly cause leg pain but the disc bulge with no nerve compression as described in your report is unlikely to be causing back pain.
The reason for bone scan may be a suspicion for spondylolysis
which is one of the causes of back pain in teenagers. However, MRI would demonstrate hyperintensity indicating edema around the lysis. A CT scan
will confirm the diagnosis of spondylolysis. The bone scan in your case is likely ordered to doubly rule out the possibility of spondylolysis.
Hope this is helpful. Let me know if I can be of further assistance. Wish you the best for upcoming exams.
